The concrete is easy to dry, so it is necessary to use the concrete mixer truck during the transportation, especially for the long-distance transportation, because the mixer truck can not only realize the long-distance transportation, but also continuously mix the concrete in the transportation process. Don't let it dry to powder. During this period, the tires are often in contact with the ground. How to judge whether the mixer tire should be changed:

1、轮胎胎面花纹深度

1. Tread depth of tire

胎面花纹的厚度一定要大于1.6毫米，如果你经常驾车行驶在摩擦力低的湿滑路面上，能保证胎面花纹厚度是上述数值的两倍。

The thickness of tread pattern must be greater than 1.6 mm. If you often drive on wet roads with low friction, you can ensure that the tread pattern thickness is twice the above value.

2、胎面花纹磨损指示线

2. Tread pattern wear indicator line

混凝土搅拌车胎面花纹磨损指示线。当磨损到达一定程度 这些隐藏在胎面沟壑中的指示线就呈现出来。胎面花纹磨损指示线为扁平的橡胶条，与胎面纵向垂直镶嵌在胎面沟壑中。如果轮胎上的几乎所有指示线都清晰可见，意味着你需要尽快更换轮胎了。

Wear indicator line of tread pattern of concrete mixer truck. When the wear reaches a certain level, the indication lines hidden in the tread grooves appear. The tread pattern wear indicator line is a flat rubber strip, which is embedded in the tread groove vertically with the tread. If almost all of the indicator lines on the tire are clearly visible, it means that you need to change the tire as soon as possible.

3、轮胎侧壁裂纹

3. Tire sidewall crack

轮胎上存在的问题并不是全部集中在胎面上，轮胎侧壁也会出现一些毛病。通过观察查找轮胎侧壁上那些肉眼直接可见的裂痕和切口。这些细小的沟槽预示着轮胎上未来可能出现的漏气裂缝，甚引发轮胎的爆裂。所以在轮胎侧壁裂纹比较严重时，建议考虑更换轮胎。

The problems existing in the tire are not all concentrated on the tread, and there are also some problems on the sidewall of the tire. Look for cracks and cuts on the sidewall of the tire that are visible to the naked eye. These small grooves indicate that there may be air leakage cracks on the tire in the future, and even cause the tire to burst. Therefore, it is recommended to replace the tire when the sidewall crack is serious.

4、轮胎上的凸起和起泡

4. Bumps and blisters on tires

有些情况下，混凝土搅拌车轮胎的外表面会因为强度不够，导致高出正常轮胎表面的凸起和起泡。这就如同血管中出现的动脉瘤，轮胎也面临类似的状况，如果没有及时检修，胎面上强度不足的区域有可能引发突然的爆裂。

In some cases, the outer surface of concrete mixer tire will bulge and blister higher than the normal tire surface due to insufficient strength. This is just like an aneurysm in a blood vessel. If the tire is not repaired in time, the area with insufficient strength on the tread may cause a sudden burst.

如果发现混凝土搅拌车的轮胎满足以上条件之一，说明轮胎该换了，不管轮胎是否爆胎，也不管用了多长时间，都应该换掉需要更换的轮胎换上新的轮胎，确保驾驶。

If it is found that the tire of the concrete mixer meets one of the above conditions, it means that the tire should be replaced. No matter whether the tire is burst or how long it takes, the tire that needs to be replaced should be replaced with a new one to ensure driving safety.
